Antibiotic resistance represents a significant public health challenge in the current century. The β‐lactam antibiotics, together with carbapenems, are inactivated by zinc‐dependent bacterial enzymes called metallo‐β‐lactamases (MBLs). Presently there no clinically permitted MBL inhibitors, and to produce such drugs, it is indispensable comprehend their inhibitory action. We investigated an efficient synthesis of pyridine‐embedded 1,3,4‐oxadiazole hybrids (3a-c) antimicrobial activity against different microbial strains. compounds were characterized spectral techniques (viz., IR, NMR, mass). vitro antibacterial antifungal was also performed; displayed excellent activity. silico docking studies evaluated proteins New Delhi Metallo-Beta-lactamase-1 (NDM‐1) Mycobacterium tuberculosis enoyl reductase (INHA). All demonstrated binding affinity for docked proteins. Additionally, molecular dynamics disclosed (4a-c) .

Abstract Because of its importance in medicinal chemistry, scientific researchers have been interested incorporating sulfamethazine developing biologically active candidates. To achieve this, several synthetic approaches adopted. The adopted included condensation with electrophilic reactants, coupling nucleophilic aromatics and methylene compounds, Knoevenagel condensation, Doebner Miller reaction, microwave‐assisted click cycloaddition, green reaction routes, multicomponent reaction. Linking this molecular scaffold to a variety heterocycles the last 10 years furnished set potential anti‐inflammatory, antiviral, anticancer, antiparkinsonian, neuroprotective, antidiabetic candidates targeting H5N1 NA, epidermal growth factor receptor, acetylcholinesterase (AChE), butylcholinesterase (BChE), human carbonic anhydrase ( h CA), α‐amylase, α‐glucosidase. This review reports all approaches, biological activities studied, structure‐activity relationship analyses, mechanistic investigations reported organic sulfamethazine‐incorporating molecules throughout 2015–2024, based on information retrieved from three search engines: Scopus, PubMed, Google Scholar.

The search for novel drug scaffolds that can improve effectiveness and safety through conjugates is a promising approach. Consequently, constitute dynamic field of study advancement within medicinal chemistry. This research demonstrates the conjugation diclofenac mefenamic acid with sulfa drugs their screening urease inhibition. These conjugates' structural confirmation was performed using elemental analysis spectroscopic methods, including IR, 1H NMR, 13C NMR. Diclofenac conjugated sulfanilamide (4), sulfacetamide (10), (12), sulfamethoxazole (17) found potent demonstrated inhibition competitively, IC50 (μM) values 3.59 ± 0.07, 5.49 0.34, 7.92 0.27, 8.35 0.26, respectively. sulfathiazole (6), sulfamerazine (8), sulfaguanidine (11), while sulfisoxazole (13), (14), sulfadiazine (15) exhibited mixed mode were 16.19 0.21, 9.50 0.28, 4.35 0.23, 15.86 0.25, 14.80 Furthermore, molecular docking studies employed to predict binding pose competitive inhibitors at active site. generated stable complexes protein observed dynamics (MD) simulations, where no conformational changes occurred throughout simulations. results highlight potential approved therapeutic molecule give rise new categories pharmacological agents similarity sulfonamides urea allows them compete site enzyme. Sulfonamides nonsteroidal anti-inflammatory (NSAIDs) interact hydrophobically enzyme, which may disturb its structure catalytic activity. Therefore, these be helpful in development treatment variety illnesses enzyme involved.

AbstractTo explore the new mode of action and reduce side effects, making conjugates existing drugs is becoming an attractive tool in realm medicinal chemistry. In this work, we exploited approach synthesized to assess their activities against enzymes involved different pathological conditions. Specifically, design involving acetylsalicylic acid sulfa drugs, validating newly crafted using techniques like IR, 1HNMR, 13CNMR, elemental analysis. These underwent assessment for ability inhibit cyclooxygenase-2 (COX-2), urease enzymes, anti-inflammatory potential. A competitive inhibition was observed conjugated with sulfanilamide, sulfacetamide, sulfadiazine IC50 2.49 ± 0.35 µM, 6.21 0.28 6.57 0.44 respectively. Remarkably, acid-sulfamethoxazole conjugate exhibited exceptional activity, effectively curtailing induced edema by 83.7%, a result akin reference drug indomethacin's performance (86.8%). Additionally, it demonstrated comparable COX-2 (75.8%) selective inhibitor celecoxib that 77.1% at 10 µM concentration. To deepen our understanding, employed molecular docking predict binding interactions inhibitors receptors. MD simulations were carried out, confirming stability inhibitor-target complexes throughout simulation period, devoid significant conformational changes. Collectively, research underscores potential coupling approved compounds usher novel categories pharmacological agents, holding promise addressing wide spectrum disorders enzymes.Communicated Ramaswamy H.
